That night, the theater was full of people. Including Sylvie who was shocked to see an old face.

'And though it's clear, though it was always clear that this was never meant to be. If you happen to remember, stop and think of me. Think of August when the world was green. Don't think about the way things might have been. Think of me, think of me waking, silent, and resigned. Imagine me trying too hard to put you from my mind. Think of me, please say you'll think of me whatever else you choose to do. There will never be a day when I won't think of you!'

From Box Five, Sylvie watched Loki sing. They were once friends when his father was still alive. But, Sylvie had to leave because her parents had business to take care of. So to see Loki all grown up since the last time was a dream.

'Can it be? Can it be Loki? Brava! Brava!" Sylvie clapped early for him, 'Long ago, it seems so long ago. How young and innocent we were. He may not remember me but I remember him.'

'Flowers fade, the fruits of summer fade. They have their seasons, so do we. But please promise me that sometimes, you will think,' Loki paused and started vocalizing before belting out, 'Of me!'

The song ended and the show ended. Loki now knew it was worth the wait. The theater cheered for him as he bowed to them. When the curtains closed and Loki was backstage, he was surrounded by ballet girls with Bucky among them. They all congratulated Loki on his performance. Natasha got their attention and congratulated Loki too saying the Angel of Music would be pleased. There was no doubt about it.

She was pleased. She was proud. Natasha turned to the girls disappointed in their performance. The ballet girls had to rehearse again. The Phantom wouldn't be happy with their dancing. As they left, a voice was heard. It was Loki's Angel, congratulating him. Bucky tried to get Loki out of his trance at the voice. When he did, Loki turned to him.

'Where in the world have you been hiding? Really, you were perfect. I only wish I knew your secret. Who is this new tutor?' Bucky asked smiling.

Loki wasn't sure whether to tell him or not. The two have been friends for years and he never told him about the angel. But, Loki trusts him.

'Father once spoke of an Angel. I used to dream she'd appear. Now as I sing I can sense her and I know she's here,' Loki went into his dressing room, took his costume off, and changed into his robes.

'Here in this room, she calls me softly. Somewhere inside, hiding. Somehow I know she's always with me. She, the unseen genius.'

'I watched your face from the shadows, distant through all the applause. I hear your voice in the darkness yet the words aren't yours,' Bucky said as Loki sat at his desk and looked in the mirror.

'Angel of music, guide, and guardian. Grant to me your glory!'

'Who is this Angel? This...'

'Angel of music, hide no longer. Secret and strange Angel,' the friends said.

'She's with me even now,' Loki said.

'Your hands are cold,' Bucky said taking his hands

'All around.'

'Your face, Loki, it's white!'

'It frightens me!'

'Don't be frightened...'

Natasha got their attention. Bucky knew it was partly for him because he left ballet rehearsals. Natasha told him to go back to them while she gave Loki a letter. It wasn't much. At most, it was hints leading to Sylvie. But Loki didn't want to believe it. He hasn't seen her in years. Surely she wouldn't recognize him now. He ignored it for now and finished taking off his makeup and accessories. Meanwhile, the managers were showing Sylvie to Loki's dressing room. She had a rose for him. When they arrived, Sylvie asked to be unaccompanied while visiting Loki. They let her and left. Sylvie walked in.

"Loki Laufeyson, where is your green scarf?" Sylvie asked him

"Madame?" Loki asked confused.

"Well, you can't have lost it. After all the trouble I took. I was just 14 and soaked to the skin..."

"Because you had run into the sea to fetch my scarf," Loki turned to her, "Oh, Sylvie. So it is you!"

"Loki," Sylvie gave him a red rose, 'Little Lotte let his mind wander.'

"You remember that too?'

'Little Lotte thought: Am I fonder of dolls?'

'Or of goblins or shoes?' they asked smiling

'Or of riddles of frocks,' Loki said smiling at the memory of their old game

"Those picnics in the attic? Or of chocolates?' Sylvie asked smiling.

"Father playing the violin."

"As we read to each other dark stories of the North," Sylvie laughed.

'No. What I love best, Lotte said, is when I'm asleep in my bed and the Angel of Music sings songs in my head!'

'The Angel of Music sings songs in my head!' They sang

Loki looked at an old picture of Laufey, "Father said, 'When I'm in heaven, child, I will send the Angel of Music to you'. Well, father is dead, Sylvie, and I have been visited by the Angel of Music."

"No doubt of it. And now we'll go to supper!"

"No, Sylvie, the Angel of Music is very strict."

"I shan't keep you up late!"

"No-!" 

"You must change," Sylvie interrupted, "I must get my hat. Two minutes. Little Lotte."

Sylvie left. Loki can't go with Sylvie. The Angel of music is waiting for him. But the Angel of Music was already there, enraged. How dare this woman come and try to steal Loki from her! Over the years she's been teaching him, she's fallen in love with him. And she will not let Sylvie take Loki from her!

"Things have changed, Sylvie," Loki said out loud.

'Insolent girl! This slave of fashion basking in your glory! Ignorant fool! This brave young suitor, sharing in my triumph!' The Angel, and Phantom, (Y/N), sang out scaring Loki at her anger.

'Angel! I hear you! Speak, I listen... Stay by my side, guide me! Angel, my soul was weak forgive me... Enter at last, Master!' Loki sang

(Y/N) softened up, 'Flattering child. You shall know me. See why in shadow I hide. Look at your face in the mirror, I am there inside!'

She was in the mirror. From what Loki could see, she wore a mask covering all of her right side and her left, covering her forehead. Her skin was a perfect (S/C), her eyes a brilliant (E/C) and he could faintly see (H/L) (H/C). This was his Angel of Music.

'Angel of Music! Guide and guardian! Grant to me your glory! Angel of Music! Hide no longer! Come to me, strange angel!' Loki said looking at his Angel.

'I am your Angel of Music. Come to me, Angel of Music,' The mirror opened to reveal more of her. 

She wore a black dress small, but flowy enough to be stealthy and avoid getting caught. On top, she wore a white blouse with a black waistcoat and blazer. Sitting perfectly on her shoulders was a long cape that barely touched the floor. Atop her head was a black fedora with some black feathers. It was leaning over to the right so she could try and hide her mask a little. But Loki took no notice of her appearance. (Y/N) had him hypnotized by her voice

'I am your Angel of Music. Come to me: Angel of Music.'

And, just like that, she had him. She closed the mirror as Sylvie came in looking for Loki. But he was long gone with Angel of Music.
